Overview

Cat Large Wheel Dozers are designed with durability built in, ensuring maximum availability through multiple life cycles. With optimized performance and simplified serviceability, our machines allow you to move more material efficiently and safely at a lower cost per ton. Engineered for your demanding work in large dozing applications, the 844K Wheel Dozer is the largest in the Cat Wheel Dozer line and is an ideal match for large mining operations, power generating utilities, the general contracting industry and wherever mobility, versatility and compaction is needed.

Enhance strength in key pin areas through the use of one piece castings.

Push Beam and Push Arm Dozer Arrangement

To ensure long life and reliability, solid one piece push beams are through-width, not merely attached to the side of the frame. In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.

Cat MineStar System

Cat MineStar System is the industry’s broadest suite of integrated mine operations and mobile equipment management technologies, configurable to suit your operation’s needs. Its capability sets - Fleet, Terrain, Detect, Health and Command - contain a range of technologies that let you manage everything from fleet assignment and condition monitoring to remote and autonomous control. The 844K can take advantage of many of these advanced technologies, some of which are standard out of the factory.

Fleet

Fleet provides comprehensive, real-time machine tracking, assignment and productivity management, giving you a comprehensive overview of all operations from anywhere in the world.

Terrain for Loading

Terrain with your 844K enables high-precision management of loading operations through the use of guidance technology. It increases 844K’s productivity and provides you real-time feedback for improved efficiency.

Detect

Detect helps increase operator awareness, enhancing safety at your operation. It includes a range of capabilities designed to assist the operator with areas of limited visibility around fixed and mobile equipment.

Sustainability

Sustainable Benefits

Engine Idle Shutdown can help you save fuel by avoiding unnecessary idling.

Reduce waste to the environment with our maintenance free batteries.

The 844K is built for multiple lives. To assist with maximizing machine life, Caterpillar provides a number of sustainable options such as our Reman and Certified Rebuild programs. In these programs, reused or remanufactured components can deliver cost savings of 40 to 70 percent, which lowers operating cost.

Caterpillar offers retrofit packages to bring new features to older machines, maximizing your resource. And, when you go through the Cat Certified Rebuild program, these retrofit kits are part of the rebuild process.
